8000 BC: Another Antarctic Ice Shelf collaped

We are reading all this doom and gloom about the collapse of the Antarctic Ice shelves, as if this is unprecedented in human's time on earth. It isn't.

The George VI ice shelf lies at 70 degrees south. As of today, this shelf is not showing signs of collapse due to global warming. The George VI shelf is 100 to 500 meters thick. It's location is shown on the picture below.

The author's point out

"Some studies in the northern Antarctic Peninsula suggest iceshelfcollapse in the mid-Holocene (Pudsey and Evans, 2001). To date, ice shelves farther south (south of 708S) have shown no catastrophic breakup, although some ice-shelf fronts are in retreat. This paper presents the first evidence of an early Holocene collapse of one of these more southern ice shelves." M. J. Bentley, “Early Holocene Retreat of the George VI Ice Shelf, Antarctic Peninsula,” Geology, 33(2005):173-176, p. 173

Now, given the 'consensus' that the earth's present temperature is 'unprecedented' what do these scientists conclude?

“Thus, both atmospheric and oceanographic warming occurred immediately prior to, and coincident with, ice-shelf collapse. Finally, the timing of the iceshelf collapse predates collapse at more northern Antarctic Peninsula sites (Pudsey and Evans, 2001), that has been linked to a mid-Holocene warm period (Jones et al., 2000; Hodgson et al., 2004). We have three main conclusions: (1) High-resolution multiproxy sediment records show that the George VI Ice Shelf collapsed in the early Holocene. (2) The timing of collapse is consistent with both iceand marine sediment–core evidence of early Holocene warmth. (3) The collapse of a currently extant ice shelf shows that early Holocene natural ocean-atmosphere variability in the Antarctic Peninsula was greater than the recent, potentially anthropogenically influenced changes.”M. J. Bentley, “Early Holocene Retreat of the George VI Ice Shelf, Antarctic Peninsula,” Geology, 33(2005):173-176, p.176

My bolding. The reality is that in spite of what the hysteriacs say, today's warming is not as warm as it was 8000 years ago. The science of geology shows it yet they ignore it.

About Me

I have had 39 years experience looking for oil and gas around the world, from Scotland, to Algeria, to the East Coast of the United States, South Texas, West Texas, the Rocky Mountain region, Alaska and China. I have found 33 oil fields and drilled my share of dry holes. The various positions held by me include: Manager of Geophysical Training for a major oil Co., Chief Geophysicist for a small independent oil company, Geophysical Manager - Onshore Gulf Coast, Geophysical Manager--Gulf of Mexico and Chief Geophysicist for China , Manager Geophysics for the US Offshore, Geophysical Manager for the North Sea, Director of Integrated Technology, Director of Exploration for China with a large independent oil company and lived in Beijing China. I speak Mandarin (not fluent but able to communicate). Currently I have my own geophysical consulting firm, living in Houston
